Description

Technical Field

[0001] This invention relates to the field of power facility accessories technology. Specifically, it relates to a guy wire protective sleeve. Background Technology

[0002] Guy wire sheaths are protective devices used for guy wires on utility poles. They are mainly divided into three categories: telecommunications and power guy wire sheaths, and passageway warning tubes. Most are made of PVC and feature insulation, strong weather resistance, and easy installation. The main body is a plastic round tube with a longitudinal slit, which achieves quick closure through a groove and convex edge interlocking structure. It can cover specifications such as diameters of 30-160mm and lengths of 1500-3000mm. This assembly structure requires consideration of the slit size and the thickness of the utility pole's guy wire, as well as the sheath wall thickness; otherwise, installation difficulty will increase. Furthermore, the protruding parts at the interlocking points are not conducive to the adhesion of reflective marking film, which can lead to peeling or damage to the reflective marking film from the protrusions. Summary of the Invention

[0003] Therefore, the technical problem to be solved by the present invention is to provide a diagonal guy wire protective sleeve. The use of a semi-tube splicing structure can make the outer wall of the protective tube relatively flat, reduce the impact of protrusions on the adhesion of reflective marking film, and reduce the probability of reflective marking film being easily damaged or peeled off due to poor adhesion quality.

[0004] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0005] A guy wire protective sleeve includes a protective tube and a protective cover. The protective cover is detachably connected to the upper end of the protective tube. Reflective marking films are provided on the side walls of both the protective cover and the protective tube. Both the protective cover and the protective tube adopt a radially split structure. The protective tube includes a first half-tube structure and a second half-tube structure, which are detachably connected. The radial cross-section of the arc-shaped portion of the inner wall of the first half-tube structure includes a first arc segment, a second arc segment, and a third arc segment. The second arc segment is located between the first arc segment and the third arc segment, and the centers of the first arc segment and the third arc segment coincide. The distance L between the center O1 of the first arc segment and the center O2 of the second arc segment, the radius R1 of the first arc segment, the radius R2 of the second arc segment, and the outer diameter R0 of the protective tube satisfy the following formula:

[0006] α×(R1-R2)≤L≤β×(R0-R2);

[0007] In the formula, α ranges from 1.05 to 1.2; β ranges from 0.55 to 0.65.

[0008] The radial cross-sectional structure of the arc-shaped portion of the inner wall of the second half-tube structure is the same as that of the arc-shaped portion of the inner wall of the first half-tube structure in the aforementioned guy wire protective sleeve.

[0009] The aforementioned guy wire protective sleeve has the first half-pipe structure and the second half-pipe structure interlocked.

[0010] The aforementioned guy wire protective sleeve has a first L-shaped groove formed on the inner wall of the two side edges of the first half-tube structure along the axial direction of the first half-tube structure. The bottom of the first L-shaped groove has a first trapezoidal groove, wider inside and narrower outside, along the axial direction of the first half-tube structure. The ratio of the upper base to the lower base of the trapezoidal cross-section of the first trapezoidal groove is 1:(1.05~1.2). A second L-shaped groove is formed on the outer wall of the two side edges of the second half-tube structure along the axial direction of the second half-tube structure. The bottom of the second L-shaped groove is formed along the axial direction of the second half-tube structure. A second trapezoidal groove, wider at the inside and narrower at the outside, is provided. The ratio of the upper base to the lower base of the trapezoidal cross-section of the second trapezoidal groove is 1:(1.05~1.2). When the first half-tube structure and the second half-tube structure are engaged, the openings of the first trapezoidal groove and the second trapezoidal groove are positioned opposite each other. One end of the X-shaped elastic connector is disposed in the first trapezoidal groove, and the other end of the X-shaped elastic connector is disposed in the second trapezoidal groove. Furthermore, the X-shaped elastic connector is interference-fitted with both the first trapezoidal groove and the second trapezoidal groove.

[0011] The aforementioned guy wire protective sleeve has fluorescent plastic components arranged along the axial direction of the protective tube on the outer wall of the first half-tube structure and the outer wall of the second half-tube structure.

[0012] The aforementioned guy wire protective sleeve, wherein the fluorescent plastic component includes a fluorescent plastic strip, a connecting plate and a cylindrical elastic mounting strip, wherein the fluorescent plastic strip is fixedly connected to the cylindrical elastic mounting strip through the connecting plate, and the cylindrical elastic mounting strip is disposed in a fitting groove, wherein the fitting groove is formed on the outer wall of the first half-tube structure and the second half-tube structure.

[0013] The aforementioned guy wire protective sleeve includes a first half-cover and a second half-cover. The first half-cover includes a first lower half-cylinder, a first cover plate structure, and a first upper half-cylinder. The second half-cover includes a second lower half-cylinder, a second cover plate structure, and a second upper half-cylinder. When the first half-cover and the second half-cover are detachably connected, the first cover plate structure and the second cover plate structure are engaged.

[0014] When the first half-cover and the second half-cover are detachably connected, the first lower half-cylinder and the second lower half-cylinder are engaged, and the first upper half-cylinder and the second upper half-cylinder are engaged.

[0015] In the aforementioned guy wire protective sleeve, when the first upper half-cylinder and the second upper half-cylinder are combined to form an upper cylinder, a first annular groove is formed on the upper end face of the upper cylinder along the axial direction of the upper cylinder. The cross-section of the bottom of the first annular groove is an arc structure including a first arc segment, a second arc segment, and a third arc segment. The radius r1 of the first arc segment, the radius r2 of the second arc segment, and the radius r3 of the third arc segment satisfy the relationship: r2 < r3 < r1. The arc length L1 of the first arc segment, the arc length L2 of the second arc segment, and the arc length L3 of the third arc segment satisfy the relationship: L3 < L1 < L2.

[0016] In the aforementioned guy wire protective sleeve, when the first lower half-cylinder and the second lower half-cylinder are combined to form the lower cylinder, a second annular groove is provided on the outer wall of the lower end of the lower cylinder along the axial direction of the lower cylinder; when the first half-cover and the second half-cover are assembled into the protective cover, a fastening adhesive strip is provided in the second annular groove.

[0017] The beneficial effects of this invention are as follows:

[0018] 1. This invention redesigns the inner wall structure of the protective tube and adjusts the thickness distribution of the protective tube wall. This increases the average thickness of the protective tube wall while ensuring good flexibility of the semi-tube structure. This allows one semi-tube structure to be opened when assembling two semi-tube structures into a complete protective tube. At the same time, it ensures the elastic recovery force of the two semi-tube structures, making the two semi-tube structures more stable when interlocked. Furthermore, it ensures that the outer wall of the complete protective tube is relatively flat, which facilitates the application of reflective marking film and helps to improve the service life of reflective marking film.

[0019] 2. The present invention adds a fluorescent plastic component to the outer wall of the protective tube, which can increase the indicated width of the protective tube and make it easier to distinguish the protective tube from a distance. At the same time, the fluorescent material can be used to emit fluorescence after absorbing light to provide a marker for pedestrians or cyclists.

[0020] 3. A first annular groove for filling sealant is provided on the upper cylinder of the protective cover. The first annular groove increases the bonding strength between the sealant and the protective cover plate, and at the same time can prevent rainwater from seeping into the sealant and the protective cover plate, which would cause the sealant to peel off.

Detailed Implementation

[0031] like Figure 1 As shown, the guy wire protective sleeve of the present invention includes a protective tube 100 and a protective cover 200. The protective cover 200 is detachably connected to the upper end of the protective tube 100. Reflective marking films 300 are provided on the side walls of the protective cover 200 and the protective tube 100. Preferably, the protective cover 200 and the protective tube 100 are threaded together. Both the protective cover 200 and the protective tube 100 adopt a radial split structure.

[0032] Among them, such as Figures 2-5As shown, the protective tube 100 includes a first half-tube structure 101 and a second half-tube structure 104, which are detachably connected. The radial cross-sectional structure of the arc-shaped portion of the inner wall of the second half-tube structure 104 is the same as that of the arc-shaped portion of the inner wall of the first half-tube structure 101. The radial cross-section of the arc-shaped portion of the inner wall of the first half-tube structure 101 includes a first arc segment, a second arc segment, and a third arc segment. The second arc segment is disposed between the first arc segment and the third arc segment, and the centers of the first arc segment and the third arc segment coincide. The distance L between the center O1 of the first arc segment and the center O2 of the second arc segment, the radius R1 of the first arc segment, the radius R2 of the second arc segment, and the outer diameter R0 of the protective tube 100 satisfy the following formula:

[0033] α×(R1-R2)≤L≤β×(R0-R2);

[0034] In the formula, α ranges from 1.05 to 1.2; β ranges from 0.55 to 0.65.

[0035] To facilitate installation and assembly, manufacturers often make the protective tube 100 relatively thin according to standards. However, a thinner tube wall results in a shorter lifespan and increased susceptibility to damage upon impact. Increasing the wall thickness, on the other hand, complicates assembly. Therefore, in this invention, the first half-tube structure 101 is designed to be thinner in the middle and slightly thicker on both sides. This aims to increase the wall thickness while ensuring ease of assembly. For example, the existing protective tube 100 of the guy wire protection sleeve has a wall thickness of 2.6–2.8 mm. According to the structure designed in this invention, the wall thickness at the thicker section can reach 4–5 mm, while the wall thickness at the thinner section is 2.4–3.2 mm. Because the thinnest part of the wall is narrower, it is less susceptible to impact when the guy wire protection sleeve is subjected to shock, thus preventing damage and improving the lifespan of the guy wire protection sleeve of this invention.

[0036] In this invention, the first half-tube structure 101 and the second half-tube structure 104 are snapped together. Specifically, as shown... Figure 2 and Figure 5 As shown, a first L-shaped groove 102 is formed on the inner wall of the two side edges of the first semi-tube structure 101 along the axial direction of the first semi-tube structure 101. A first trapezoidal groove 103, wider inside and narrower outside, is formed at the bottom of the first L-shaped groove 102 along the axial direction of the first semi-tube structure 101. The ratio of the upper base to the lower base of the trapezoidal cross-section of the first trapezoidal groove 103 is 1:1.13. Figure 3 and Figure 5As shown, a second L-shaped groove 105 is formed on the outer wall of the two side edges of the second half-tube structure 104 along the axial direction of the second half-tube structure 104. A second trapezoidal groove 106 with a wider inner diameter and a narrower outer diameter is formed at the bottom of the second L-shaped groove 105 along the axial direction of the second half-tube structure 104. The ratio of the upper base to the lower base of the trapezoidal cross section of the second trapezoidal groove 106 is 1:1.13. When the first half-tube structure 101 and the second half-tube structure 104 are engaged, the openings of the first trapezoidal groove 103 and the second trapezoidal groove 106 are positioned opposite each other. One end of the X-shaped elastic connector 107 is disposed in the first trapezoidal groove 103, and the other end of the X-shaped elastic connector 107 is disposed in the second trapezoidal groove 106. Furthermore, the X-shaped elastic connector 107 is interference-fitted with both the first trapezoidal groove 103 and the second trapezoidal groove 106.

[0037] When assembling the first half-tube structure 101 and the second structure into the protective tube 100, a sliding assembly can be adopted, that is, the first end of the first half-tube structure 101 and the second end of the second half-tube structure 104 are snapped together, and then slid along the axial direction of the protective tube 100 until the assembly is completed. This assembly method requires that one end of the X-shaped elastic connector 107 be fixed in the first trapezoidal groove 103 or the second trapezoidal groove 106. Alternatively, the following assembly method can be adopted: one end of the X-shaped elastic connector 107 is placed in the first trapezoidal groove 103, and then one side of the first half-tube structure 101 and one side of the second half-tube structure 104 are assembled together by tucking the other end of one X-shaped elastic connector 107 into the second trapezoidal groove 106. Then, the other side of the first half-tube structure 101 is bent outward, and then the second X-shaped elastic connector 107 is pressed into another second trapezoidal groove 106 to complete the assembly.

[0038] In this invention, the X-shaped elastic connector 107 is used as a connector not only for ease of assembly, but also because when the connection between the first half-tube structure 101 and the second half-tube structure 104 is squeezed, the X-shaped elastic connector 107 can withstand a large compressive force. Furthermore, if the X-shaped elastic connector 107 is not bonded to the first half-tube structure 101 and the second half-tube structure 104 respectively with adhesive, the X-shaped elastic connector 107, which has come out of the first trapezoidal groove 103 or the second trapezoidal groove 106, can be pressed back in by the squeezing action of the reflective marking film 300.

[0039] Given that the guy wire protective sleeve serves a warning function, the reflective marking film 300 on the sleeve will reflect light under illumination to remind drivers or pedestrians that a guy wire is located at the location of the sleeve. To enhance the warning effect of the guy wire protective sleeve, the outer diameter of the protective tube 100 is usually increased so that people can see its location more clearly. In this invention, fluorescent plastic components are provided along the axial direction of the protective tube 100 on the outer walls of the first half-tube structure 101 and the second half-tube structure 104.

[0040] Among them, such as Figure 5 As shown, the fluorescent plastic component includes a fluorescent plastic strip 110, a connecting plate, and a cylindrical elastic mounting strip 108. The fluorescent plastic strip 110 is fixedly connected to the cylindrical elastic mounting strip 108 via the connecting plate. The cylindrical elastic mounting strip 108 is disposed within a fitting groove 400, which is formed on the outer walls of the first half-tube structure 101 and the second half-tube structure 104. By using the fluorescent plastic component to increase the visibility range of the guy wire protective sleeve, not only can the visibility range of the guy wire protective sleeve be increased without increasing the outer diameter of the protective tube 100, but the fluorescent effect of the fluorescent plastic component can also provide a warning effect for pedestrians at night, especially after the fluorescent plastic component is illuminated by light, the fluorescent effect of the fluorescent plastic component becomes more obvious.

[0041] Given that the protective cover 200 also needs to be detachably assembled with the protective tube 100, the structural stability of the protective cover 200 after assembly needs to be considered. Therefore, in this invention, as... Figure 1 and Figures 6-9 As shown, the protective cover 200 includes a first half-cover and a second half-cover. The first half-cover includes a first lower half-cylinder 213, a first cover plate structure, and a first upper half-cylinder 214. The second half-cover includes a second lower half-cylinder 223, a second cover plate structure, and a second upper half-cylinder 224. When the first half-cover and the second half-cover are detachably connected, the first cover plate structure and the second cover plate structure are engaged.

[0042] Specifically, such as Figure 6 and Figure 8 As shown, the first cover plate structure includes a first substrate 211 and a first boss 212. The first boss 212 is radially disposed on the lower surface of the first substrate 211, and a first mounting through groove is provided on the first substrate 211 opposite to the position of the first boss 212. A snap-fit ​​connector 215 is provided on the lower surface of the first substrate 211. Figure 7 and Figure 9As shown, the second cover structure includes a second substrate 221 and a second protrusion 222. The second protrusion 222 is radially disposed on the upper surface of the first substrate 211. A second mounting through groove is provided on the second substrate 221 opposite to the position of the second protrusion 222, and a snap-fit ​​groove 225 is provided on the upper surface of the second substrate 221. In this invention, both the first half-cover and the second half-cover can be manufactured by integral injection molding.

[0043] In the first half-cover, the outer wall of the first upper half-cylinder 214 is fixedly connected to the first boss 212 and the first substrate 211 respectively, and the outer wall of the first substrate 211 is fixedly connected to the inner wall of the first lower half-cylinder 213.

[0044] In the second half-cover, the outer wall of the second upper half-cylinder 224 is fixedly connected to the second boss 222 and the second substrate 221 respectively, and the outer wall of the second substrate 221 is fixedly connected to the inner wall of the second lower half-cylinder 223.

[0045] When the first half-cover and the second half-cover are detachably connected, the snap-fit ​​connector 215 is disposed within the snap-fit ​​groove 225, and the first lower half-cylinder 213 and the second lower half-cylinder 223 snap-fit ​​together, and the first upper half-cylinder 214 and the second upper half-cylinder 224 snap-fit ​​together. Furthermore, when the first lower half-cylinder 213 and the second lower half-cylinder 223 are combined to form the lower cylinder, a second annular groove 240 is provided on the outer wall of the lower end of the lower cylinder along the axial direction of the lower cylinder. When the first half-cover and the second half-cover are assembled into the protective cover 200, a tightening adhesive strip is provided within the second annular groove 240. This tightening adhesive strip enhances the structural stability of the protective cover 200 and the stability of the threaded connection between the protective cover 200 and the protective tube 100.

[0046] Due to weather conditions, a certain amount of dust will appear in the air. This dust will settle when air movement is weak, causing dust to accumulate on the guy wires of utility poles. This dust will flow with rainwater through the gap between the guy wire and the protective cover 200 into the guy wire inside the protective tube 100. Some dust will drip down with the rainwater and accumulate on the inner wall of the protective tube 100. The chemical substances adsorbed on the dust or the chemicals it carries may accelerate the aging of the protective tube 100, thus shortening its service life. Therefore, to reduce the amount of rainwater flowing into the protective tube 100 through the gap between the guy wire and the protective cover 200, waterproof adhesive or... Other common adhesives are used, but if a large amount of adhesive is applied to the guy wire of the utility pole, it will cause trouble for later cleaning. If less adhesive is applied, the adhesive will not adhere firmly to the protective cover 200. Therefore, when the first upper cylinder 214 and the second upper cylinder 224 are combined to form the upper cylinder, the upper end face of the upper cylinder is provided with a first annular groove 230 around the axial direction of the upper cylinder. The cross-section of the bottom of the first annular groove 230 is an arc structure including a first arc segment, a second arc segment and a third arc segment. The radius r1 of the first arc segment, the radius r2 of the second arc segment and the radius r3 of the third arc segment satisfy the relationship: r2 < r3 < r1. The arc length L1 of the first arc segment, the arc length L2 of the second arc segment and the arc length L3 of the third arc segment satisfy the relationship: L3 < L1 < L2. The first annular groove 230 with the above structure allows for the application of more adhesive to the end of the upper cylinder. Furthermore, during the peeling of the adhesive after curing, the adhesive can be easily separated from the guy wire by pulling the protective cover 200. This is because the presence of the first annular groove 230 not only increases the contact area between the adhesive and the upper end of the upper cylinder, but also utilizes the inward curve of the upper end of the third arc segment to weaken the adhesion between the adhesive near the upper end of the upper cylinder and the guy wire, thus facilitating the peeling of the adhesive from the guy wire. Additionally, it prevents water from seeping into the gap between the adhesive and the upper cylinder when using non-waterproof adhesive to seal the gap between the upper cylinder and the guy wire, thereby avoiding damage to the adhesive structure between the adhesive and the upper cylinder.

[0047] When using the guy wire protective sleeve of this invention, one end of the X-shaped elastic connector 107 can be first inserted into the first trapezoidal groove 103. Then, the first side of the first half-tube structure 101 and the second side of the second half-tube structure 104 are assembled, so that the two ends of the X-shaped elastic connector 107 on this side are respectively set in the first trapezoidal groove 103 and the second trapezoidal groove 106, forming a tubular structure with one side open. Then, the tubular structure is fitted onto the guy wire of the utility pole. Then, the second side of the first half-tube structure 101 is bent outward, while the first side of the second half-tube structure 104 is bent inward. The other end of the X-shaped elastic connector 107 on the second side of the first half-tube structure 101 is pressed into the second trapezoidal groove 106 on the second side of the second half-tube structure 104 and pressed tightly to complete the assembly of the protective tube 100. Then, the protective cover 200 is assembled on the guy wire of the utility pole above the protective tube 100, and the upper cylinder and the lower cylinder are fitted onto the guy wire of the utility pole. Then, the protective cover 200 is threaded to the protective tube 100. Next, the reflective marking film 300 is affixed, and then waterproof glue is applied to the upper end of the upper cylinder to seal the gap between the guy wire of the utility pole and the upper cylinder.

[0048] Although the guy wire protective sleeve of this invention has a more complex structure than some existing guy wire protective sleeves on the market, its service life is increased by more than 80%, and the reflective marking film 300 does not exhibit localized peeling after impact, sun exposure, and rain. While increasing the wall thickness, the guy wire protective sleeve of this invention still maintains its ease of assembly. Furthermore, upon impact, by locally thinning the inner wall, while keeping the outer diameter of the protective tube 100 unchanged, relative sliding occurs between the locally thinned tube wall and the guy wire of the utility pole. This allows the guy wire to slide towards the thinner section of the tube wall, creating a buffer and preventing tearing of the tube wall under the pressure of the guy wire, thereby improving the service life of the protective tube 100.

[0049] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of the claims of this patent application.
